TELAUTOGRAPH.

SPECIFICATION forming part of Letters Iatent No. 567,325, dated September 8, 1896.

Application filed June 7, 1895. Serial No. 551,943. (No model.)

T at whom it may concern:

Be it known that I, GEORGE S. TIFFANY, a citizen of the United States, residing at Highland Park, county of Lake, and State of llli- 5. nois,have invented certain new anduseful Improvements in Telautographs, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

My invention relates to telautographs in which the pen at the receiving-station is moved by some motive power controlled from the transmitting-station, and has for its particular object to provide means for charg- I 5 ing the batteries of the various instruments of the system from a central station. For this purpose one'or two of the line-wires are ,used as charging-wires, and these may be the ordinary escapement-circuits from which the go controlling or driving impulses are sent or other wire or wiresof the system. It is desirable that the apparatus should embody an automatic switch at each -distant station, which can be electrically operated from the i central station, although I do not intend to limit my broad claims to the use of a switch which isautomatic.

In the drawings annexed, forming a part of the specification, Figure 1 shows in diagram that part of the connections involved in this improvement between the central station and a distant station. Figs. 2, 3, and 4 are respectively a side, plan, and end view of an automatic switch which may be used 3 5 in this improvement.

' As shown herein, the means used for transmitting the charging-current consist of the two escapement-lines of the system. The automatic switch is placed in these lines between the central station and the receivingstation to which it appertains. The switch consists of a magnet A, the armature of which is divided and is normally drawn back by retractile spring S against the stop F. The ar- 4 5 mature is provided with two springs O O, normally incontact with plates E E, attached to the armature. The post J carries contactpins D D in such a position as to make contact, respectively, with the springs C 0 when the armature is thrown forward. The device is provided with a low non-inductive resistance-coil O.

The circuit of the line-wires, which are lettered RE and LE, is as follows; The current entering through line RE divides and passes in multiple are through the resistance 0 and the coils of magn et A, thence to spring O,plate E, and wire as to the right esoapement-magnet of the receiving instrument and ground. From ground the path of the circuit is through the left escapement-magnet of the receiving instrument, line y, plate E, spring 0 to-line-wire LE. This is the position of the parts when the instrument is ready for the reception of a message.- The resistance of the coils of the magnet A is such that the reverse current used On the escapement-lines will give rise to such inductive resistance that the current will be diverted from the magnet A to the shunt through the non-inductive resistance O, leaving the magnet A normally deenergized and its armature in the position shown in Fig. 2 of the drawings. Vhen the operator at the central station turns on the charging-current by shifting the two-armed switch T, the charging-current, being continuous in one direction, energizes magnet A, and armature B is attracted, the effect of this being to break the contacts between G O and E E, respectively, and to bring G G into contact with D D, respectively. D D are connected, respectively, through Wires w z to the two poles of the batteries Z Z. The circuit from the charging battery lines RE LE, therefore, now passes through the coils of magnet A and partially through resistance 0 to the battery. When the Operator atthe central station has thrown back the switch T, the magnet A is deenergized, releases its armature, the charging-circuits to the bat- 9o tery are broken, and the circuits resume their normal receiving position.

While, as I have said, my invention may be applied by the use of either one or two line-wires, it is preferable to use two in order to have a complete metallic circuit between the generator and the battery being charged, and my invention-therefore includes the provision of connections whereby such complete metallic circuit may be made. Two batteries 10o or a divided battery are frequently employed, and my invention includes an arrangement of circuits for connecting such batteries in series with the line-wires.

What is claimed is 1. In a telautographic system, the combination of a line wire or wires, means for sending pulsations to the line for operating the receiving-pen, a charging-generator and a switch for throwing the same into line at one station, and a battery and magnetically controlled automatic switch in a main-line circuit at the distant station, the automatic switch being irresponsive to the normal working pulsations on the line, but being operated by the current from the charginggenerator so as to throw said battery into the charging-circuit, substantially as described.

2. In a telautographic system, the combination of a line wire or wires, means for sending pulsations of successively-alternating polarity to line for operating the receiving-pen, a charging-generator and a switch for throwing the same into line at one station, a battery and a magnetically-controlled automatic switch in the main-line circuit at the distant station, and devices whereby the automatic switch is caused to be unaffected by the normal pulsations on the line while the instrument is writing but is operated by the current from the charginggenerator so as to throw the said battery into the charging-circuit, substantially as described.

3. In an automatic switch for charging the batteries of a telautographic system, the com bination of a magnet and a resistance placed in multiple arc in the main-line circuit, the magnet and resistance being so made relatively to each other and to the circuit that the magnet is not energized by the ordinary alternating currents of the main lines, and an armature-lever provided with circuit makers and breakers, whereby when the chargingbattery current is thrown on, the magnet is energized and the arm ature drawn up and the circuit made between the chargin g-circ uit and the battery, substantially as set forth.

4. In a telautographic system, the combina tion of two stations, the two escapement-lines connecting the stations, a source of electrical energy and a switch at the first station, an automatic charging-switch at the second station consisting of a magnet and resistance in multiple arc in the circuit of the said two linewires, said magnet and resistance being so made that the magnet is not normally ener gized by the reverse impulses on the lines during the operation of the instrument, but that it is energized by a charging-current, an armature for said magnet, and circuit connections controlled thereby leading to the battery at the second station, whereby on-the manipulation of the said switch at the first station, the charging-current being thrown on the line, the magnet of the automatic switch is energized and caused to attract its armature and the battery at the second station is thereby brought into circuit with the said two linewires, substantially as set forth.

5. In a telautograph, the combination of two stations, a line wire or wires connecting the stations, a charging-generator and means for throwing the same into line-circuit at one station, and at the other station a battery and mechanism for connecting said battery with the line-circuit, said mechanism being irresponsive to the normal working-current on the line, but being operated by the current from the charging-generator so as to throw said battery into the chargingcircuit, substantially as set forth.

6. The combination of two t-elautographic stations, two line-wires, a charging-generator and means for throwing the same into line at one station, and at the other station a battery and means operated by the charging-current for connecting the opposite terminals of the battery with the line-wires to form a closed metallic circuit with the generator, substan tially as set forth.

7. The combination of two telautographic stations, two line-wires, a charging-generator and means for throwing the same into line at one station, and at the other station a battery and mechanism electrically controlled by the charging-current for establishing a connection between the said line-wires and the two terminals of said battery, said mechanism being irresponsive to the normal working currents traversing said line-wires but being operated to throw the said battery into the said circuit by the current of the charging-generator, substantially as set forth.

8. The combination of two telautographic stations, two line-wires, a charging-generator and means for throwing the same into line at one station, and at the other station a battery in two parts having between them a ground connection, and means operated by the charging-current for connecting said two parts in series with the said line-wires so as to place the said battery and the generator in a closed metallic circuit, substantially as set forth.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
